Laminated Molded Body

Abstract

A laminated molded body is produced by coextrusion of plural types of resin materials and includes a main body ( 1 ) and, superimposed on its surface, a decorative layer ( 2 ) and a surface layer ( 3 ). The decorative layer ( 2 ) includes, in lamination with each other, a colored film ( 2 a ) of a colored resin material and a brightening film ( 2 b ) of a resin material capable of brightening the colored film ( 2 a ). Among these films, the colored film ( 2 a ) has a thickness that changes in a stepless or stepwise manner, and such a transparency that the bright film ( 2 b ) disposed inside can be observed therethrough, allowing the colored film ( 2 a ) to be observed in a bright state on the surface of the main body ( 1 ).

1 . A laminated and molded body produced by coextrusion of plural types of resin materials, and including a main body and, superimposed on its surface, a decorative layer and a surface layer, wherein: 
 the decorative layer includes, in lamination with each other, a colored film of a colored resin material and a brightening film of a resin material capable of brightening the colored film, and the colored film has a thickness that changes in a stepless or stepwise manner and such a transparency that the brightening film disposed on an inner side can be observed therethrough, allowing the colored film to be observed in a bright state on the surface of the main body.    
   
   
       2 . The laminated molded body according to  claim 1 , wherein said brightening film contains a pearl material reflecting light and exhibiting a pearly luster.  
   
   
       3 . The laminated molded body according to  claim 1 , wherein said brightening film contains a powder material reflecting light and exhibiting a metallic luster.  
   
   
       4 . The laminated molded body according to  claim 1 , wherein, among said films, the film situated on the outer side has a thickness that varies within a range of 50% with reference to the thickness of the laminated molded body.  
   
   
       5 . The laminated molded body according to  claim 1 , wherein said laminated molded body is one of a preform for blow molding process, a direct-blow molded bottle, a tube and a blow molded tube.  
   
   
       6 . The laminated molded body according to  claim 2 , wherein, among said films, the film situated on the outer side has a thickness that varies within a range of 50% with reference to the thickness of the laminated molded body.  
   
   
       7 . The laminated molded body according to  claim 3 , wherein, among said films, the film situated on the outer side has a thickness that varies within a range of 50% with reference to the thickness of the laminated molded body.  
   
   
       8 . The laminated molded body according to  claim 2 , wherein said laminated molded body is one of a preform for blow molding process, a direct-blow molded bottle, a tube and a blow molded tube.  
   
   
       9 . The laminated molded body according to  claim 3 , wherein said laminated molded body is one of a preform for blow molding process, a direct-blow molded bottle, a tube and a blow molded tube.  
   
   
       10 . The laminated molded body according to  claim 4 , wherein said laminated molded body is one of a preform for blow molding process, a direct-blow molded bottle, a tube and a blow molded tube.  
   
   
       11 . The laminated molded body according to  claim 6 , wherein said laminated molded body is one of a preform for blow molding process, a direct-blow molded bottle, a tube and a blow molded tube.  
   
   
       12 . The laminated molded body according to  claim 7 , wherein said laminated molded body is one of a preform for blow molding process, a direct-blow molded bottle, a tube and a blow molded tube.
